Appropriate braces 14a are also employed between the main. portions of the fully described; "illustrated in the accom- ZGHr TSP W-Z ms O Y H P .4;a h I rear edgeof the plate-6 to strengthen thi'sfpor-i" 7 tion ofitheq-structure and prevent tlierear edgerof theplate-(i frompressing down on the;

while the structure is heated, during operation of the stubble burner.

A rake bar, either hollow as shown or solid, and designated by the numeral 16, is carried in the ends of the plurality of U-shaped brackets 17 and secured therein by attaching members 18 past through the bar 16 and the brackets 17. The brackets 17 extend for wardly and have their bight portions 19 loosely mounted on the front bar or tube 11 and are prevented from moving forwardly on the latter by stop members 20 extended transversely through bight portions 19. The rake teeth 21 are extended on an incline through the rake bar 16, the teeth 21 being inclined rearwardly so as to effectively ride on the surface and raise to upright position all fallen stubble or stalks.

A transverse burner pipe or nozzle 22 is extended beneath the plate '6, throughout the length thereof and has on its underside a plurality of spaced burner jets 23 directly above the lower ends of the rake teeth 21. The burner pipe or nozzle 22 is mounted on the depending end 24 of the fuel conductpipe 25, a portion 26 of which may be flex- 1 e if desired and connected with the valved discharge nozzle 27 of the fuel supply tank 28 mountedon the wagon 29 or other means employed for drawing the device over the surface. A divided flexible connection 30 is employed between the wagon 29 and the front bar 11 of the device and is shown in the form of a chain having a ring 31 removably en gaged with the clevis 32 on the end of a wagon 29, while the divided portions or ends of the chain are detachably mounted on the clevises 33-carried on the front bar 11. It may also be stated that the burner pipe or nozzle 22 is revented' from dropping away from the bottom of the plate 6, by means. of the stop collar 34 forming'part of the connection between the burner pipe or nozzle 22 and the depending end 24 of the fuel conducting pipe and resting on the upper face of the plate 6.

As the construction of the device has thus been described in detail, brief reference is now had to its use and modus operandi: As the device is drawn over the surface it rides 1 on the front curved spring arms or runners 13 and the rear curved spring arms or runners 14 thus permitting the device to travel I over an uneven surface without materially interfering with eflicient operation of the device. The rake teeth 21 will engage and'raise to upright position any fallen or leaning stubble or grain stalks and the like and present them to the destroying blaze directed downwardlyfrom the burner jets 23. The

'* weight of the rake bar 16 and rake teeth 21 will'result in thelatter being maintained on the surface and as the supporting brackets 17 for the rake bar 16 are free to swing on the front bar 11 of the device, this efficient functioning of the rake teeth 21 will continue,

the brackets 17, near their.

regardless of the unevenness of the surface and the resulting raising or dropping of one or more of the curved spring arms or runners 13 and 14. Owing to the connection and the portion 26 of the pipe 25, both being flexible, the device is further permitted to operate efliciently over an uneven surface without interfering with the feeding of the fuel to the burner pipe or nozzle 22 or drawing of the device over the surface by the wa on29 or other draft means.

rom the foregoing description taken in connection with the accompanying drawings, it will be manifest that a stubble burner is provided that will fulfill all the necessary reqliliirements of such a device but as many 0 anges could be made in the above description and many apparently widely different embodiments of my invention may be constructed within the scope of the appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawings, shall be interpreted as illustrative and not in a limited sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 2-- I 1. Astubble burner includin a transversely elongated deflector plate; f ront and rear curved spring runners supported beneath said deflector plate; angle irons on the upper face of the forward and rear edges of said burner plate to'brace the same; brace bars between said rear curved spring runners and the rear ed e of said deflector plate; a front bar suspended below the front edge of said deflector plate; a rake structure mounted for swingingmovement on said front bar and beneath said deflector plate; a burner beneath said deflector plate andabove the said rake structure ;;-a fuel supply tank connected to said burner; and draft means extended from said front bar'of the said stubble burner.

2. A stubble burner including a transversely elongated deflector plate having trailer rear spring supports, angular brackets depending from the front edge of said deflector plate; a lower ends of said angular'brackets'; forward spring supports attached to said bar; a rake structure mounted for swinging movement on said front bar; and a burnerat the underside of said deflector plate with burner jets directed toward the working ends of said rake. i v
